Total fee-based value-added service subscribers grew by 22 percent year on year to 135 million, primarily driven by video and music streaming services, the company said.

"In 2017, Tencent made important strategic moves that reinforced our leadership," said Ma Huateng, chairman and CEO of Tencent, citing the company's leading position in video services, which had the most mobile daily active users and monthly subscriptions.

"Looking forward, we are substantially increasing our investment in areas including video, payment, cloud, AI technology and smart retail, which will impact our near term earnings but which we believe can generate long term value and growth opportunities," Ma said.

Monthly active user accounts of instant messaging product QQ was 783 million last year, down 9.8 percent from a year earlier. Combined monthly active user accounts of Weixin and WeChat were 989 million, up 11.2 percent.
